The requirements are cross-referenced to dedicated page, similarly to
TODO and bug lists.
Also updated / improved documentation for some texture / image formats.
All HTML code and Doxygen shortcuts such as @c, @b and @em are now
rewritten using Markdown syntax, which makes it more readable.
Also updated Doxyfile. Doxygen 1.8 at least is required to generate
the documentation now.
These classes are meant to be used in the same texture updating
functions as Trade::ImageData due to static polymorphism. In addition to
Trade::ImageData, which is read-only, these classes support updating the
dimensions and data. Image2D and ImageBuffer2D can update the data also
from framebuffer.
Start of AbstractImporter rework - Trade namespace will contain simple
classes usable for exchanging data with other formats, importers will
not depend on any OpenGL functionality, they will just provide access to
plain data.
